Description
UltraClear® Biological Clarifier is a natural pond clarifier powered by beneficial bacteria and enzymes to improve clarity and balance without harsh chemicals.
When suspended particles and organic debris cause hazy or murky water, Biological Clarifier helps reduce the buildup that clouds your pond. Unlike chemical flocculants that provide only temporary particle clumping, this biological formula supports long-term clarity while contributing to a healthier pond ecosystem.
Perfect for spring start-up, routine pond maintenance, or addressing seasonal cloudiness, Biological Clarifier is easy to apply — just pour evenly across your pond. Safe, natural, and eco-friendly, it helps maintain a clear, balanced, and thriving pond environment year-round.

We love this product to keep our pond clear.
It did not work
Getting ready to order my 4th bottle. My pond is only about250 gallons, so it lasts. I've had my pond (koi, goldfish etc) for 20 years and tried many products. This is by far the best.
fish are happy
Had a problem with an order and they quickly made it right. Good prices on products. I will continue to buy from this seller.
